Device for simulating comprehensive influence of foundation pit excavation and multi-echelon precipitation on tunnel
The invention provides a device for simulating the comprehensive influence of foundation pit excavation and multi-echelon precipitation on a tunnel. The device mainly comprises a model box, a tunnel structure system, an underground water control system, a foundation pit structure system and a measurement system.The foundation pit structure and the tunnel structure are arranged, sandy soil is usedfor simulating a confined water layer, a confined water head is simulated by the underground water control system, and various data in the test process are collected in real time in combination with the measurement system. By means of the system, the influence of the coupling effect of foundation pit excavation and pressure reduction and precipitation on a proximity tunnel can be simulated, the influence of foundation pit multi-echelon pressure reduction and precipitation on a regional seepage field is studied, and the influence of tunnel or foundation pit local seepage on structural safety isevaluated.
本发明提供了一种模拟基坑开挖及多梯次降水对隧道综合影响的装置，该装置主要包括模型箱、隧道结构系统、地下水控制系统、基坑结构系统和测量系统：布置基坑结构及隧道结构，利用砂性土模拟承压水层，其承压水头由地下水控制系统模拟，结合测量系统实时采集试验过程中的各种数据。通过该体系，可以模拟基坑开挖及减压降水的耦合效应对近接隧道的影响，研究基坑多梯次减压降水对区域渗流场的影响，进行隧道或基坑局部渗漏对结构安全影响的评价等。
